Abstract

Major advances have recently been made in the identification and management of tachydysrhythmias in children. These include diagnostic improvements in both noninvasive techniques (24-hour ambulatory ECG monitoring and transtelephonic ECG transmission) and invasive techniques (His bundle recordings and intracardiac stimulation studies). In consort, there also have been new developments in tachyarrhythmia therapy. For example, propranolol has been popularized for treating tachycardias in children; the dosage range has been modified and higher doses are now used with safety, when necessary. Further, the calcium channel blocking agent, verapamil, has become accepted in Europe and South America as an effective drug for acute and chronic treatment of supraventricular tachycardia (SVT) in children and is scheduled for widespread use in the United States. The most exciting development in invasive treatment has been the use of surgical techniques and pacemakers for management of certain patients with severe or persistent forms of tachydysrhythmias.
